             *
             * ## Best practices
             *
             * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)
             * doesn't matter, they can technically be in any order. However, this can be confusing to others that trying to
             * understand the language definition because, normally, the order of tokens matters in Prism grammars.
             *
             * Therefore, it is encouraged to order overwriting tokens according to the positions of the overwritten tokens.
             * Furthermore, all non-overwriting tokens should be placed after the overwriting ones.
             *
             * @param {string} id The id of the language to extend. This has to be a key in `Prism.languages`.
             * @param {Grammar} redef The new tokens to append.
             * @returns {Grammar} The new language created.
             * @public
             * @example
             * Prism.languages['css-with-colors'] = Prism.languages.extend('css', {
             *     // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
             *     // at its original position
             *     'comment': { ... },
             *     // CSS doesn't have a 'color' token, so this token will be appended
             *     'color': /\b(?:red|green|blue)\b/

            /**
             * Inserts tokens _before_ another token in a language definition or any other grammar.
             *
             * ## Usage
             *
             * This helper method makes it easy to modify existing languages. For example, the CSS language definition
             * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
             * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
             * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
             * this:
             *
             * ```js
             * Prism.languages.markup.style = {
             *     // token
             * };
             * ```
             *
             * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
             * before existing tokens. For the CSS example above, you would use it like this:
             *
             * ```js
             * Prism.languages.insertBefore('markup', 'cdata', {
             *     'style': {
             *         // token
             *     }
             * });
             * ```
             *
             * ## Special cases
             *
             * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
             * will be ignored.
             *
             * This behavior can be used to insert tokens after `before`:
             *
             * ```js
             * Prism.languages.insertBefore('markup', 'comment', {
             *     'comment': Prism.languages.markup.comment,
             *     // tokens after 'comment'
             * });
             * ```
             *
             * ## Limitations
             *
             * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
             * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
             * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
             * deleting properties which is necessary to insert at arbitrary positions.
             *
             * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
             * Instead, it will create a new object and replace all references to the target object with the new one. This
             * can be done without temporarily deleting properties, so the iteration order is well-defined.
             *
             * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
             * you hold the target object in a variable, then the value of the variable will not change.
             *
             * ```js
             * var oldMarkup = Prism.languages.markup;
             * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
             *
             * assert(oldMarkup !== Prism.languages.markup);
             * assert(newMarkup === Prism.languages.markup);
             * ```
             *
             * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
             * object to be modified.
             * @param {string} before The key to insert before.
             * @param {Grammar} insert An object containing the key-value pairs to be inserted.
             * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
             * object to be modified.
